  • Publication number: 20240123400
    Abstract: Methods and systems integrate direct carbon capture and desalination processes to various degrees, benefiting from synergies in the combined processes. A method includes receiving an input liquid comprising a brine reject stream from a water treatment facility and pre-treating the input liquid. The pre-treatment includes one or more of filtration, a reverse osmosis, and ion exchange. The method also includes performing an electrochemical process on the input liquid to produce at least one hydroxide-rich stream and capturing CO2 from air using the hydroxide-rich stream and a passive air capture system, thereby producing a liquid carbonate solution containing air-captured CO2. In some cases byproducts and recovered water can be used by the water treatment facility and/or the carbon capture process.

  • Publication number: 20230191322
    Abstract: A method for capturing and sequestering carbon dioxide (CO2) includes receiving and performing an electrochemical process on the input liquid including water and a salt to produce at least one hydroxide-rich stream, and then capturing CO2 from air using the hydroxide-rich stream and a passive air capture system, thereby producing a liquid carbonate solution containing air-captured CO2. Optional steps include disposing of the liquid carbonate solution, precipitating air-captured CO2 from the liquid carbonate solution as solid carbonate and/or a slurry of carbonate, and mixing the liquid carbonate solution with a hydrogen-rich stream produced by the electrochemical process to generate gaseous CO2. Various integrations and synergies among CO2 capture, renewable energy, water desalination, and metal and mineral extraction are provided.

  • Patent number: 10441536
    Abstract: Described herein are micronized powder particles of colistimethate sodium wherein at least 50% by volume of the micronized particles have a diameter of less than 7 micrometers but not less than 3 micrometers and the powder has a total moisture content of from 5 to 10% by weight, for use in the treatment of a pulmonary infection by powder inhalation, wherein the colistimethate sodium is not separated into component form. The micronized powder particles of colistimethate sodium are useful in the treatment of infections caused by gram-negative bacteria, particularly in patients suffering from cystic fibrosis.
